/ Best trousers for scottish winter?

So, being a complete numpty, I've managed to shred my pair of Marmot Precip pants with my front-points this season.

Ordinarily, I wear powerstretch pants, a thin softshell layer and then overtrousers on top, but having knackered the waterproofs, I'm looking to upgrade to something a bit more substantial - can I get some recommendations on salopettes (preferably with braces and those helpful reinforced ankle patches...)?

In reply to Steve Perry: I have recently got these too. If the weather is cold and not too windy or wet then I would say soft shell with long johns is fine. But if its damp or potentially wet I hate the over trouser thing, so the paramo aspiras are better - giving a reasonable level of protection and warmth without any other layers under or over. They have removeable foam knees too - I am forever banging my knees on ice so I like that.
